Can you take prilocaine while breastfeeding?
What LactMed says
The National Library of Medicine’s own summary, quoted in full. We do not write a verdict of our own on this question, and we do not compress theirs into a label.
No information is available on the use of prilocaine during breastfeeding. Based on the low excretion of other local anesthetics into breastmilk, a single dose of prilocaine injected during breastfeeding, such as for a dental procedure, is unlikely to adversely affect the breastfed infant. However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Topical application of prilocaine to the mother is unlikely to affect her breastfed infant if it is applied away from the breast. Only water-miscible cream or gel products should be applied to the breast because ointments may expose the infant to high levels of mineral paraffins via licking.

Frequently asked questions
Can you take prilocaine while breastfeeding?
No information is available on the use of prilocaine during breastfeeding. The full record is quoted on this page, and the decision is one to make with the person who prescribed it — LactMed itself states it is not a substitute for professional judgement.
Does prilocaine pass into breastmilk?
LactMed's measured drug levels for prilocaine are quoted in full on this page, under "How much gets into breastmilk".
Do I need to pump and dump after taking prilocaine?
LactMed does not frame its records that way — it reports measured drug levels in milk and what has been observed in breastfed infants, which is what this page quotes. "Pump and dump" advice for a specific drug and dose should come from your clinician or a pharmacist, not from a general rule.
